Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1 and Figure 2, an ultra-narrow beam angle LED floodlight provided by the utility model includes a front cover, a glass lampshade, an optical device, a lamp housing radiator, a power supply, a rear cover and stand. The glass lampshade is a high-transmittance glass lampshade, and the optical device is an optical device with an ultra-narrow beam angle. An aluminum substrate is also fixed between the optical device and the lamp housing heat sink, and the aluminum substrate is the aluminum substrate of the LED and the circuit. An aging-resistant sealing ring is arranged between the front cover and the radiator of the lamp housing, and the radiator of the lamp housing is disc-shaped. This shape increases the overall heat dissipation area of the lamp housing and improves the heat dissipation effect. The power supply is set in the power cavity, and the power cavity is separated from the heat sink of the lamp housing. This separation structure completely isolates the two heat sources of the power cavity and the optical device, which greatly improves the heat dissipation efficiency. In addition, there are waterproof joints on the back cover.

The two legs of the bracket are fixed on the radiator of the lamp housing. Between the radiator of the lamp housing and the power supply chamber, there are sequentially arranged disc-shaped connectors and installation and fixing bases, and a sealing rubber ring is also arranged between the installation and fixing base and the power supply chamber.

The installation method of the utility model is as follows: install the optical device with ultra-narrow beam angle on the aluminum substrate with LED and circuit, and then lock it into the radiator of the lamp housing; install the rubber cable, power supply and Connect the aluminum substrate and lock it in the power supply cavity; pass the rubber cable through the waterproof connector and the power supply cavity in turn and lock it, then put on the sealing rubber ring and lock it on the lamp housing radiator; put the high-transmittance glass lampshade on The anti-aging sealing ring is locked to the radiator of the lamp housing together with the front cover; then the bracket and the radiator of the lamp housing are connected with stainless steel screws; the fixing base and the bracket are fixed with stainless steel screws.

The utility model provides an ultra-narrow beam angle LED floodlight, the light energy is utilized to the maximum, so as to achieve the effect of energy saving and environmental protection; the aging-resistant silicon rubber sealing ring is adopted, so that the light energy of the LED floodlight can be utilized to the maximum extent , good heat dissipation effect, good sealing performance, prolonging the service life of the lamp.
